HARROW.

SPECIFICATION formingpart of Letters Patent No. 223,334, dated January6, 1880.

Application filed November 10, 1879.

To all whom it may concern:

Be it known that I, JAMES P. GAGE, of Traer, in the county of Tama andState of Iowa, have invented certain new and useful Improvements inHarrows; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, and tothe letters of reference marked thereon, which form partof this specification.

The nature of my invention consists in the construction and arrangementof a barrow as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure 1 is a plan view of the barrow, Fig. 2, a detail side view of oneof the teeth and Fig. 3, a cross-section of the same. I

My harrow is made in three sections, as shown. The front or main sectionconsists of three or more parallel bars, A A, held rigidly together bymeans of metal straps or bars B B and O U. The metal straps B B run nearthe ends at right angles to the bars A A, and their rear ends areconnected by a metal bar, D, running in rear of and parallel with thebars A. The straps or braces O 0 run diag' onally, and have their rearends united together and to the center of the bar I). In rear of themain harrow-section thus formed are two adjustable side sections, whichare each composed of three or more parallel bars, A A, connectedtogether by metal bars B B. These are not united rigidly, but so thatthe harrowsection can be spread outward when desired. It is then heldrigid by means of a slotted brace, O, pivoted to one bar and passingover a bolt, a, in another bar, and a thumbnut, F, screwed thereon. Thetwo rear sections are connected to the bar D of the front section bymeans of clevises I) and links cl, substantially as shown.

This barrow is particularly adapted to barrowing corn, as it isadjustable to any ground,

and also adjustable sidewise by loosening the thumb-nuts F and movingthe back sections outward to the various widths of marking, so that theentire ground between the rows can be cultivated without disturbing thehills in any way.

To the front section of the harrow is 0011- nected a tongue, G, by meansof the side arms, ff, bearings i '11, and rod h. This tongue is veryessential in the working of the barrow, as it obviates any liability ofthe horses getting back on the harrow, and at the same time it guidesthe harrow so that no two teeth run in the same track.

I I represent the harrowteeth, made of smoothpolished steel, taperingall the way down, so that no rubbish can accumulate on them, thus makingthem self-cleaning. The teeth are made in diamond form having thediameter greater one way than the other, thus making them capable ofbeing adjusted to a perfect standing cutter for sod or a cultivator bychanging their position in the barrow.

Each tooth is formed with a shank, I, the lower part of which is squareor diamondshaped, as shown at m, so that it cannot turn accidentally inthe harrow. The upper part, a, of the shank is made round and threaded,to receive a nut for fastening the tooth in the barrow.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the front or main section, composed of the bars A,metal straps B O, and bar D, and the adjustable rear sections, composedof the bars A, straps B, and slotted adjustingbraces G, with bolts a andthumb-nuts F, substantially as and for the purposes herein set forth.

In testimony that I. claim the foregoing as my own I affix my signaturein presence of two witnesses.

JAMES PIKE GAGE.
